I've been job hunting for about eight months.
A few weeks ago I went to an interview and handed off my car to the valet guy.
As I was waiting for the elevator I heard him tell his coworker that he would kill for a coffee, so after my interview I stopped at the cafe in the lobby and grabbed one for him.
He was super grateful and asked for my business card.
]I gave it to him, thinking maybe he wanted to send me a thank you email or something.
The next day I got a call from the manager at this big staffing agency in our city. She was the valet guy's cousin and he asked her to call me. I ended up meeting with her in person, and after only a week she found me my dream job. Today was my first day, and it went perfectly.
Be nice to everyone, all the time.
